iOS 9.3 is coming in the Spring and will introduce Night Shift as well as a number of other new features.
New iMac Deliveries to Be Delayed Until Early Next Year?
The new iMac uses some advanced welding techniques as well as a new manufacturing process for the LCD screen that was rumored to delay the introduction of the iMac. Apple has run into difficulties ramping up production on its more recent product launches as the company pushes the envelope on what is physically possible.
During Apple's most recent earnings call, Tim Cook talked briefly about the constraints the company faces during the all-important holiday quarter:
In terms of general shortages on the iMac, we’ll be constrained for the full quarter in a significant way, part of that is that we’re beginning shipping the 21.5-inch iMac in November and the 27-inch in December. And so there will be a short amount of time during the quarter to manufacture and ramp those and I expect the demand to be robust. So we will have a significant shortage there.
